Traffic pattern: For simple calls (such as Circulate, Walk & Dodge, etc.)
move directly to your ending footprints. For more complex calls,
start the call working distorted, blend into a normal setup, complete
the call normally, and then have the resulting Ends move away from
the Center in order to re-establish the Butterfly footprints.

Sometimes the caller may wish you to start the call in your Butterfly
but finish in a normal setup. In these cases the caller will put a suffix such as
'To Normal Waves', 'To A Line', 'To Columns', etc. (e.g., Butterfly
Transfer The Column To Normal Waves).

Note: A Butterfly can also be
T-Bone
in which case you do your part working within your set of distorted Columns.

"X" CONCEPT[C4](Jim Davis):
An "X" occupies the same footprints as a Butterfly but is considered to be two diagonal Columns
which cross over each other in the middle.
An "X" Circulate is the same as a Butterfly Circulate, except that the #3 dancers
(in-facing Centers) do a Concentric Box Crossover Circulate
(Jaywalk with each other).
